Thanks for the response. I know there are a million guys who say that if you have a track machine you would never go back to wheels. I have no issues with the wheeled Carlton but I hate, hate, hate taking the wheels off and on and off and on to go through a narrow gate. I live in Oklahoma and we have very hot summers with high humidity. That means instant sweating. Ha! I would love to have a track machine just for that purpose ... push a button and the tracks go in or out. With tracks, I think I would lose about 10% of my work for people who have manicured lawns with several stumps. It isn't always possible to make a straight run at several stumps on a property. Also, I am nearly 70 years old, so dragging sheets of plywood around to go from stump to stump isn't something I would be willing to do. Nearly all my customers would not mind a divot or two out of their lawn but those who spend fortunes on their landscape would not like that. My point in all this is, do you go the extra mile and lay plywood down for such jobs or are you good enough that you don't find that to be an issue? Do any of your customers worry about you damaging their lawns? One other thing, the Carlton SP7015 can be a bit tippy on any incline if you are traversing the ground parallel to a slope. How is your track unit in those situations? Other than taking the wheels on and off, I have never had a job I couldn't do with the wheeled unit.
